The load cell in my dyno was very sensitive the ambient temperature. I would calibrate my load cell every time I ran the dyno.What are some signs of a pump going bad on a dyno? My engines are all of a sudden showing way low on power, 2 that I've fooled with, and 1 that I have touched. The one I havent touched is almost 1 hp off from just the 15th. Or I'm wondering if my load cell is going bad?
If you hang a 10 pound weight, as pictured, the strain gauge will put out an analog signal. My dyno hardware had a analog to digital converter. That digital number could be displayed on the computer. What ever that number was, I could tell the software that that number represented 10 foot-pounds of torque. I then removed the weight. During the run, As that number increased or decreased, the computer would display it as the curve, using that number as a baseline.The method al showed might be the answer to testing the load cell .
If you put10 lbs on the arm it should show 10 or real close .
Simple way to monitor it .
